These socks can be made from the 4 colors of leftover yarn produced from the Helix Striped Spiral Nightcap. When choosing yarn for this project, be sure to choose a very smooth yarn. This will reduce the inevitable tangling. The pattern is written for short row heels. It would be inadvisable to attempt these socks in two-at-a-time fashion, because there would be 32 different strands of yarn in play at once.
